Infinity Plus (sometimes stylized as infinity plus and infinityplus) was a science fiction webzine active from 1997 to 2007, specializing in reviews, interviews, and professionally written fiction. It was founded by Keith Brooke (who took a "deliberately elitist approach"); Nick Gevers and Paul Barnett were associate editors. As of 2018, it continues to exist as a small press.
